I am making a game Pong, and have been struggling with the collision aspect between the baal hitting off the paddle. I have created a Class, to draw a rectangle, to work with collision however I dont know how to assign the rectangle to the images of the ball and paddle.

Consider I have a rectangle like this:
Point p1(100,100);
Point p2(300,200);
Graph_lib::Rectangle r(p1,p2);
And also I have a function that takes a rectangle and returns a Point of that, say, top-left corner of that rectangle. For example:
Point N(Graph_lib::Rectangle R1);
My question is that, first, how to send that Rectangle r(p1,p2) to the Point N(Graph_lib::Rectangle R1) function? And then, how to return a Point from that function?

how to use 3 variables to represent a rectangle in a grid instead of using 4. The traditional way is to use (x,y) (x2,y2). I propose using (x,l,h).In the traditional way as you probably know, (x,y) is the left op most corner, and (x2,y2) is the bottom right most corner. In the way I am proposing X is the left side, l is the length of the top side, and also the length of the bottom. 'h' is the height of the left and right. I think it's obvious how these three can define a rectangle same as the four.

I am not sure how to format it because it is only drawing one and it does not move across the screen. I thought this section of code would work and loop through each object and make each one move but it does not.

enemyPosition = new Rectangle(rectangleList[i].X + 2, rectangleList[i].Y ,enemyPosition.Width,enemyPosition.Height);

I am new to C and am unfortunately racking my brain against this simple assignment. I believe the task is to produce a rectangle out of asterisks using while loops, yet I can only produce an "L" shape. We were given a code, with syntax errors included.We are to correct the errors and test.

It seems that my program will ask the user for the number of rectangles and trapezoids but will fail to compute the area under the curve from the user input. Therefore, I believe I have a logical error somewhere or I'm forgetting to call something somewhere.

// subtracting the area of two circles from a rectangle

The problem says:
Define functions n(), s(), e(), w(), center(), ne(), se(), sw() and nw(). Each takes a Rectangle argument and returns a Point. These functions define connection points on and in the rectangle. For example, nw® is the northwest (top-left corner) of a rectangle called r.
I wrote below code for that:
#include <Simple_window.h>
Point n(const Graph_lib::Rectangle& r);
Point s(const Graph_lib::Rectangle& r);
Point e(const Graph_lib::Rectangle& r);
Point w(const Graph_lib::Rectangle& r);
Point ne(const Graph_lib::Rectangle& r);
Point se(const Graph_lib::Rectangle& r);
[Code]...
As you see, this just mark the top-left corner of the rectangle r. In other functions I need the specifications of that rectangle, for example its height and width. How to use these specs in those functions?
I've been given the task of converting a java application to a c# windows form application. The program displays a Mandelbrot which then allows the user to zoom into. I've managed to display the Mandelbrot and even zoom. However when dragging a box to zoom, the box its self doesn't show, meaning the user cannot see what area they will be zooming into.
I believe I need to call the update function which draws the rectangle as I drag however no matter what I try, I get errors from a red cross instead of the Mandelbrot to compile errors. Here is the code that I believe is relevant.
public void update(Graphics g) {
Color color = Color.White;
Pen myPen = new Pen(color);
g.DrawImage(myBitmap, 0, 0);

View 2 Replies View RelatedHow to move a rectangle in TabPage ?
View 2 Replies View RelatedWrite a program that prompts the user to input the length of a rectangle and the width of a rectangle and then displays the rectangle's area and perimeter. The program should be broken down in 3 parts:
1. Input the length and the width (two input statements)
2. Calculate the area & perimeter (results should be saved in variables
3. print results.
Format the output so the user can easily read the results. Use the tab escape so its easy to read.

The problem is that the images don't display and the window doesn't respond.
I am writing a program to calculate a rectangle's area.
Eg.
Enter top left point: 1 1 (User input)
Enter bottom right point: 2 -1 (User input)
Top Left x = 1.000000 y: 1.000000
Bottom Right x = 2.000000 y: -1.000000
Area = 2.000000 (Program output)
It keeps on prompting me my variable r is being used without being initialized, when I think I already did so.

I'm trying to create a PPM image for a class assignment. A black rectangle with a circle at the point 225, 175 with a radius of 75. I have to use certain specific methods, so I can't use like Bresenham's really famous method for creating a circle.
The problem is that it compiles fine, and transfers to an image fine, but always says that I have a negative or zero image size.
Code:
#include "shapes.h"
int main () {
int i, j, x, y;
fprintf(stdout,"P6 width height 255
");
[Code] ....
And my header is:
Code:
#include <stdio.h>#include <math.h>
#define height 480
#define width 640
#define cy 175
#define cx 225
#define radius 75
The circle has to be filled in. I made it white. Also, i and j are unsused so far, so just ignore them.
I'm having some issues understanding why the "rectangle" in the following code isn't resizing properly. Here's the code:
#include <iostream>
using namespace std;
class Rectangle {
public:
Rectangle(double w, double h, double f)
: width(w), height(h), factor(f)
[Code] .....
I tested the code with a simple multiplication factor of "2", which should result in a new width and height of 4, but instead I get an odd value that seems be close to 4.
Output:
Numerically enter the width of the rectangle: 1
Numerically enter the height of the rectangle: 1
The width of the rectangle is: 1
The height of the rectangle is: 1
The area of the rectangle is: 1
The perimeter of the rectangle is: 4
Numerically enter a number to resize the rectangle: 2
The width of the rectangle after resizing is: 2.07408e-317
The height of the rectangle after resizing is: 2.07408e-317

I would like to know the simplest way to implement a drag and drop feature for my rectangles I draw up.
I can select the rectangles and I know I have to get the old position to equal the new position but wouldn't know how to actually do this.
I would think that I would have to put it into MouseMove but again, not sure.
